Re: Kay & thermodynamics



John K.,

I was not as clear as I should have been, hopefully this summary will be
more better. :)  I also didn't intend to place you in a position of having
to defend Kay. It was just that you happened to be the one that mentioned
him, and so I began a thread in response. You can just take this as my
thinking out loud. :)

My remarks about opening a closed system were only to indicate that there is
no inevitability towards dissipation in any open system, regardless of how
much or how little it is opened. One can think of this as being like a work
function: knowing the start and endpoints are not enough, we need to know
the path to have any idea of the work done. In this case, the "path" is the
*way* in which the closed system is opened. That will determine the
resultant behavior of the open systems, not its "endpoints" ("how much" the
system is opened). In any case, the opening of a closed system will render
any attractors of the closed system moot.

My reason for bringing up that lack of inevitability towards dissipation is
that Kay's argument seems to rest on a tacit belief in a pervasive tendency
toward dissipation in any environment. In short, he relies upon a
thermodynamic "gradient" for his argument. (see "We have argued that life is
a response to the thermodynamic imperative of dissipating gradients." in S &
K's "Order from Disorder" at:
http://www.redfish.com/research/SchneiderKay1995_OrderFromDisorder.htm) But
if all ecosystems in nature are open, then this "gradient" (which shows up
universally only in closed systems) will be absent, and his argument fails.
So, its not a question of whether we can model the open ecosystem or not.

"Self-organized" is a pretty vague term. Many times its usage refers to
situations of apparent organization caused (driven by) external gradients.
"Self-organized" in the sense of Per Bak's sandpiles rely upon a
gravitational gradient, for example.

But these kinds of "self-organized" systems are not anything like complex or
living systems. And I think it is a far leap for Kay (and Schneider) to
suggest that this kind of external driver can "force" the arising and
maintaining of living organisms. My argument above essentially invalidates
the driver he proposes, which I think invalidates the rest of his thesis.

However, as I mentioned below previously, one could conceivably generalize
his concept by referring not to a specific thermodynamic process towards
dissipation as the external driver responsible for forcing life to occur,
but rather referring to any kind of thermodynamic flow toward some attractor
as the external driver. This would then work with open as well as closed
systems.

This might salvage his argument, it would seem. That would leave him with an
external driver which could then force the arising of living organisms. But
the driver force becomes subject to the vagaries of the various ecosystems
and whatever thermodynamic gradients of whatever degree towards whatever
attractors that may or may not exist in those ecosystems. So, the
universality and viability of these gradients as a driver force is called
into question. But, still, let us proceed.

Now comes the freezing experiment I mentioned previously. The core idea is
that the freezing experiment shows that the life processes of an organism -
its "livingness" - is not tied to dynamical considerations. Freezing the
organism to near absolute zero removes all the dynamics - the molecules,
etc. cease to move, and their velocity vectors go to zero. The life
processes, or aliveness, is not tied to the dynamics of the molecules and
other structural pieces that comprise it. This can be restated as that the
life processes cannot be described by state/phase sets (either classical or
quantum). All that state information is lost when it is frozen, and when it
is reheated, the molecules would only take up random state values unless
they are somehow otherwise constrained. However, Newtonian physics
(including extensions to QM) are based on states and state-descriptions. As
such, the life-process of an organism are not describable within the
paradigm of Newtonian/QM physics.
[George Kampis gives a good description of all this in his book
"Self-Organizing Systems in Biology and Cognitive Science", sec. 5.3.4].

In regards to Kay, his notion of "self-organized" is similar to Bak's, in
that it is catastrophe-based. [see
http://www.iaia-wnc.ca/pdf/Kayetalpaper.pdf ] By freezing an organism, any
thermodynamic gradient disappears, the dynamics disappear, and the results
should be truly catastrophic!! However, this is not what actually happens,
so this is why previously had said that these experimental results
"obliterate" Kay's argument.

Tim
